Spectral Analysis of Vowels and Fricatives at Varied Levels of Dysarthria Severity for Amyotrophic Lateral Sclerosis

Chowdam Venkata Thirumala Kumar, Tanuka Bhattacharjee, Seena Vengalil, Saraswati Nashi, Madassu Keerthipriya, Yamini Belur +2
ICASSP 2024accepted

Dysarthria due to Amyotrophic Lateral Sclerosis (ALS) affects the acoustic characteristics of different speech sounds. The effects intensify with increasing severity leading to the collapse of the acoustic space of the affected individuals. With an aim to characterize such changes in the acoustic sp…

Exploring the Role of Fricatives in Classifying Healthy Subjects and Patients with Amyotrophic Lateral Sclerosis and Parkinson's Disease

Tanuka Bhattacharjee, Yamini Belur, Atchayaram Nalini, Ravi Yadav, Prasanta Kumar Ghosh
ICASSP 2023accepted

Dysarthria due to Amyotrophic Lateral Sclerosis (ALS) and Parkinson’s Disease (PD) impairs sustained phoneme productions. Vowels and fricatives get affected differently owing to the differences in their production mechanisms. This paper examines three sustained voiceless fricatives - /s/, /sh/ and /…

Static and Dynamic Source and Filter Cues for Classification of Amyotrophic Lateral Sclerosis Patients and Healthy Subjects

Tanuka Bhattacharjee, Chowdam Venkata Thirumala Kumar, Yamini Belur, Atchayaram Nalini, Ravi Yadav, Prasanta Kumar Ghosh
ICASSP 2023accepted

Dysarthria due to Amyotrophic Lateral Sclerosis (ALS) affects speech production. Even the elementary sustained vowel utterances get impaired. For these, the impairments can be in achieving vowel-specific articulatory configurations, reflected in static acoustic cues, and/or in sustaining a configura…

Effect of Noise and Model Complexity on Detection of Amyotrophic Lateral Sclerosis and Parkinson's Disease Using Pitch and MFCC

Tanuka Bhattacharjee, Jhansi Mallela, Yamini Belur, Nalini Atchayarcmf, Ravi Yadav, Pradeep Reddy +2
ICASSP 2021accepted

Dysarthria due to Amyotrophic Lateral Sclerosis (ALS) and Parkinson’s disease (PD) impacts both articulation and prosody in an individual’s speech. Complex deep neural networks exploit these cues for detection of ALS and PD. These are typically done using recordings in laboratory condition. This stu…
